I believe that more recent models have the cast fill in the floor where as the older models do not. I think I read somewhere that it was a marketing requested change & it doesn't greatly alter the actual performance of the unit.
The newest models with the 2hr ratings may have a slight...
For anyone who wants to read some serious research on the mechanics I found these two papers on then net:
1) http://josbrouwers.bwk.tue.nl/publications/Journal75x.pdf
2) http://fire.nist.gov/bfrlpubs/fire07/PDF/f07089.pdf
Calcination of gypsum board starts at 80C (176F). A temperature of 120C (248F) will drive the calcination to conclusion. This property ensures that active thermal management engages at temperatures below that which will damage paper.
Also remember that the ceramic blanket designed for a boiler furnace is not the same stuff used on a space shuttle. The thermodynamics of these types of materials have already been worked out on other forums in great detail. Its an education.
No calcs were done on exotics like actual space...
Be sure to store all of your DIY tools in the second safe. That way you don't make it easy for someone to use your own tools against you. It forces them to bring their own party favors.
Thanks guys.
I am currently using 2 of the smaller EVA units and am running at 45% - 48%.
About once every 2 weeks or so I recharge 1 of the units.
FYI
Hi Team,
I have never lived through a tornado so you are correct to say he doesn't know, but....
I would completely believe that the safe would stay in place if bolted (or very heavy) because I always question the actual amount of force applied by the tornados when I look at how weakly the...
a1abdj - please post pics of amvault after fire
Hi a1abdj,
You recently posted some fantastic pictures (on a differnt forum) of an Amvault Composit safe (identical construction to an RF6528) that went throug a total burndown. You also had some closeups of the contents. Would it be possible...
Hi All,
I purchased the Extech. It was $36 with free shipping online. It is easy to use and started providing results immediately. After 24 hours the safe interior is reading 42% - 47% min/max with an accuracy of +- 4%.
Rcmodel - I would expect that the unit would be more difficult to drill than most based on its construction. I can by the hygrometer and quite a few more EVA's (if needed) for the number of bits I would ruin drilling it.
Hi All,
I have been worried about moisture levels in my RF6528 and using a golden rod is not an option because it has no holes. Right now I have two of the smaller EVA 333 and they are only lasting about 2 weeks.
I would like to get a Hygrometer. I am warry of those for cigar humidors so...
